Alfred Voeltzkow
Alfred Voeltzkow (14 April 1860 – February 1947) was a German zoologist and botanist from Berlin, Brandenburg. He studied sciences at the universities of Heidelberg, Berlin, Freiburg, and Würzburg, receiving his doctorate at Freiburg in 1887 with a dissertation on ''Aspidogaster conchicola''. He obtained his habilitation at the University of Strasbourg, and in 1900 became a member of the Deutsche Akademie der Naturforscher Leopoldina. Voeltzkow is remembered for his scientific journeys in eastern Africa and islands of the Western Indian Ocean; (Comoros, Madagascar, Juan de Nova and Aldabra). On these expeditions, Voeltzkow collected zoological specimens of numerous genera for study and classification. Voeltzkow's best-known written works involved his African journeys, and were titled: * "''Wissenschaftliche Ergebnisse der Reisen in Madagascar und Ost-Africa in den Jahren 1889-1895''" * "''Reise in Ostafrika in den Jahren 1903-1905''". His name is associated with numerou ...

Zoologist
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the Animal, animal kingdom, including the anatomy, structure, embryology, evolution, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the a ...

Zoological Specimens
A zoological specimen is an animal or part of an animal preserved for scientific use. Various uses are: to verify the identity of a (species), to allow study, increase public knowledge of zoology. Zoological specimens are extremely diverse. Examples are bird and mammal study skins, mounted specimens, skeletal material, casts, pinned insects, dried material, animals preserved in liquid preservatives, and microscope slides. Natural history museums are repositories of zoological specimens Study skins Bird and mammal specimens are conserved as dry study skins, a form of taxidermy. The skin is removed from the animal's carcass, treated with absorbents, and filled with cotton or polyester batting (In the past plant fibres or sawdust were used). Bird specimens have a long, thin, wooden dowel wrapped in batting at their center. The dowel is often intentionally longer than the bird's body and exits at the animal's vent. This exposed dowel provides a place to handle the bird without distu ...

1860 Births
Year 186 ( CLXXXVI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ...

Paul Christoph Hennings
Paul Christoph Hennings (November 27, 1841 – October 14, 1908) was a German mycologist and herbarium curator. He discovered the study of cryptogams and mushrooms as a volunteer at the botanical garden. Although circumstances initially prevented him to study in that area, he later returned to natural sciences and eventually rose to a position at the largest herbarium in Germany. Originally interested in all non-higher plants, he specialised into mushrooms and became particularly versed in tropical species sent from abroad. Biography Borne in Heide, he was attracted early to plant sciences early and as a young man attracted the attention of director Ernst Ferdinand Nolte while a volunteer at the Botanischer Garten der Christian-Albrechts-Universität zu Kiel. After an interlude caused by the Second Schleswig War, and during which he worked in the postal services. This job, which he abhorred, forced to move a number of times until he could settle in 1867 in Hohenwestedt, where ...

Toddalia Unifoliata
''Zanthoxylum asiaticum'' is a species of plant in the family Rutaceae. Under its synonym ''Toddalia asiatica'', it was the only species in the monotypic genus ''Toddalia'', now included in '' Zanthoxylum''. It is known by the English name orange climber. Description This is a liana with woody, corky, thorny stems that climb on trees, reaching up to 10 m in length. It has shiny green citrus-scented leaves, yellow-green flowers, and orange fruits about half a cm wide that taste like orange peel. The seeds are dispersed by birds and monkeys that eat the fruits. In particular, the scaly-breasted munia prefers to nest in these trees. Distribution It is native to many countries in Africa and Asia. Examples include South Africa where in Afrikaans it is called ''ranklemoentjie'', and in Venda, ''gwambadzi''. It is very popular among the Kikuyus of Central Kenya, where it is known as ''mururue'', Mauritius, where it is known as patte poule or properly .Kamau, Loice Njeri and Peter Mat ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as ''Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unisexual, w ...

Phyllanthus Boivinianus
''Phyllanthus'' is the largest genus in the plant family Phyllanthaceae. Estimates of the number of species in this genus vary widely, from 750David J. Mabberley. 2008. ''Mabberley's Plant-Book.'' third edition (2008). Cambridge University Press. to 1200. ''Phyllanthus'' has a remarkable diversity of growth forms including annual and perennial herbs, shrubs, climbers, floating aquatics, and pachycaulous succulents. Some have flattened leaflike stems called cladodes. It has a wide variety of floral morphologies and chromosome numbers and has one of the widest range of pollen types of any seed plant genus. Despite their variety, almost all ''Phyllanthus'' species express a specific type of growth called "phyllanthoid branching" in which the vertical stems bear deciduous, floriferous (flower-bearing), plagiotropic (horizontal or oblique) stems. The leaves on the main (vertical) axes are reduced to scales called "cataphylls", while leaves on the other axes develop norma ...
